I got my hands on a free plasma TV and am trying to figure out why I have no picture but sound (fuzzy sound, nothing's plugged in).
Only test I've done so far after reading on this forum is I unplugged the top buffer board. When I did that the bottom half of the screen lit up grey for a second before dimming. I plugged it back in did the same test with the bottom board and the screen stayed all black.
Does this mean my buffer board needs to be replaced. I was going to test it until I realized my multi meter doesn't have a continuity setting, unless someone can tell me how to do it without that setting?
Another common problem I read with these tv's is with the power board and a bad capacitor. I bought some capacitors before I found out that there was sound so I've kind of ruled out the capacitor being an issue now with sound...
Thanks!
